Abstract

A compressor comprises, in a container body (1), an electric element (2), and a compressive element (3) driven by the electric element (2). An oil storage (20) is provided in the bottom, and an oil pump (15) is provided to suck up oil from the oil storage (20). The oil pump (15) includes a cylinder (18) fixed to a lower support frame (14), a rotator (19) axially installed on the lower end of a driveshaft (7) and operative to rotate within an inner space of the cylinder (18), and a suction pipe (21) having an upper end connected to a communication notch (18b) formed in the cylinder (18) and a lower end inserted and arranged in the oil storage (20). In this compressor, the upper end of the suction pipe (21) is protruded into the communication notch (18b) of the cylinder (18) to configure an oil residue pool (20).
